Retrofitting of Reinforced Concrete Beam-Column Joints by Composites-Part II: Analytical Study
(Amer Concrete Inst, 2019)
Beam-column joints (BCJs) in reinforced concrete (RC) structural systems are the critical regions, especially when they are subjected to high shear demands. According to earthquake reports and joint subassembly tests in ...
Magnetic proximity effect and shell-ferromagnetism in metastable Ni50Mn45Ga5
(Amer Inst Physics, 2016)
The present study on magnetic and structural properties of Ni(50)Mn(45)G(a)5 confirms that structural metastability is an inherent property of Ni50Mn50-xXx Heusler alloys with X as In, Ga, and Sn. The ternary alloy transforms ...
Forming Behaviour at Elevated Temperature of a Laser Heat-Treated AZ31 Magnesium Alloy Sheet
(Trans Tech Publications Ltd, 2018)
The tailoring of mechanical and technological properties of the initial material in sheet metal forming has been widely investigated and successfully applied. The benefits of such an approach can be found in the improvement ...
X-ray CT monitoring of macro void development in mortars exposed to sulfate attack
(Techno-Press, 2018)
This study reports the results of nondestructive monitoring of macro void developments in mortars manufactured with both ordinary Portland cement and sulfate resistant cement. Two types of curing were utilized; tap water ...
Influence of time-dependency on elastic rock properties under constant load and its effect on tunnel stability
(Techno-Press, 2020)
In structures excavated in rock mass, load progressively increases to a level and remains constant during the construction. Rocks display different elastic properties such as E-i and v under different loading conditions ...
Use of Pinched Sluice in Albite Concentration
(Polish Mineral Eng Soc, 2017)
Albite (NaAlSi3O8) is an important industrial mineral especially for ceramic and glass production. Major Fe-containing impurity of albite ore is flaky mica minerals. This study was conducted to determine the applicability ...
Determination of Self-Healing Performance of Cementitious Composites Under Elevated CO2 Concentration by Resonant Frequency and Crack Opening Measurements
(Springer International Publishing Ag, 2018)
Global warming is a phenomenon that incontrovertibly affects daily lives of human beings in almost all aspects. Definitely, construction industry, especially concrete as most commonly used construction material, is not ...
Determination of Favorable Time Window for Infrared Inspection by Numerical Simulation of Heat Propagation in Concrete
(Springer International Publishing Ag, 2018)
Every bridge is subjected to a thorough inspection process every other year at most. Nondestructive evaluation techniques, especially noncontact methods, are gaining popularity to take part in structural health monitoring ...
Retrofitting of Reinforced Concrete Beam-Column Joints by Composites-Part I: Experimental Study
(Amer Concrete Inst, 2019)
Many of the existing reinforced concrete (RC) structures in Turkey built prior to 1999 have deficient design details due to their non-seismic design or construction flaws. In particular, the beam-column joints (BCJs) ...
Performance evaluation of a conventional closed circuit process at different cement productions
(TMMOB Maden Muhendisleri Odasi, 2017)
Performance of a conventional Polysius® two-compartment ball mill and a OSepa® high efficiency dynamic air classifier (FLSmidth) closed circuit process was investigated at the steady state conditions at CEM II type Portland ...
